7 Tips on Finding the Best Biotin Shampoo

To make sure that you find the best biotin shampoo to meet your unique needs, take a minute to consider these key features:

1. Hair Concerns

Men looking for a biotin shampoo are likely trying to tackle a concern with their hair. Whether you have thin, dry, or color-treated hair, you will want to keep the following in mind:

Thinning/Thin: The leading reason most men buy a biotin shampoo is because of hair loss. Able to build volume and soften hair, a biotin shampoo designed to strengthen hair will be a great pick for men showing the classic signs of male pattern baldness. It is worth noting that introducing a biotin shampoo into your grooming regimen will take some time to see results related to hair growth and volume. With most men experiencing a natural shedding process upon starting, expect to see increased hair volume after several weeks to a month of continued use.

Dry/Damaged: Hair that has been abused through continued use of a hair dryer or other hair styling products needs a moisturizing and health-focused shampoo to help accelerate the repair process. To prevent hair breakage and split ends, a biotin-based shampoo will not only fortify and strengthen the entire shaft of the hair follicle, but it will also work to repair the cuticles on the hair shaft as well. Once your cuticles are repaired, they can lay flat and ultimately make your hair look much healthier through a shiny or shimmering appearance.

Color-Treated: Men who regularly color their hair either at their local barbershop or through DIY solutions like Just for Men want to make sure that they treat their hair extra carefully. Biotin is considered safe to use on color-treated hair and will help to restore the natural moisture to your hair and scalp.

2. Ingredients You May Want to Add

While the focus of this guide is on Biotin (vitamin B7), we wanted to share with you a few proven ingredients that help with healthy hair growth:

  • Biotin: Found in a variety of protein-rich foods such as eggs, nuts, meats, and leafy vegetables, biotin is necessary for healthy hair growth. However, for those men who are deficient in biotin, having this ingredient within your shampoo will ensure that you set the foundation for healthy hair growth. While this may sound silly, you will want to make sure that the biotin shampoo you purchase contains biotin. Some manufacturers may list vitamin B7 instead. This is the same thing as biotin (source) and will achieve identical results.
  • Ketoconazole: Found in many of the top dandruff shampoos to combat pityriasis rosea (a scaly rash), ketoconazole has also been found to increase overall hair density for those follicles that are in the anagen phase of growth. This finding was supported in a recent study that is available on the NIH website.
  • Zinc pyrithione: An antibacterial and antifungal ingredient, Zinc pyrithione, also sometimes labeled as pyrithione zinc, is used in anit-dandruff shampoos to treat seborrheic dermatitis. While many of the best biotin shampoos don’t include this potent ingredient, should you have dandruff, you should rotate a shampoo with this ingredient into your weekly grooming routine.
  • Saw Palmetto: With 60% of patients seeing “improved” outcomes compared to baseline (source) when it comes to using saw palmetto and hair growth, it’s no wonder that this natural ingredient is finding its way into many of the leading hair growth shampoos. Helping to block dihydrotestosterone (DHT), saw palmetto is great at slowing the progress of androgenic alopecia (male pattern baldness).
  • Caffeine: While drinking a cup of joe will get you going in the morning, this very same active ingredient found in a biotin shampoo has been found to increase blood circulation to your scalp. With more blood flowing to your scalp, the hair follicles will be able to get the essential nutrients they need to grow.
  • Coconut Oil: Containing essential fatty acids, coconut oil is an effective way to improve health and strength of your hair. Coconut oil also plays a key role in scalp and hair health by gently removing buildup of sebum oil.

3. Hair Type

Every man has a unique hair type, therefore it will be best to find a biotin shampoo that matches your natural type. If you have thick hair, but perhaps are experiencing male pattern baldness, you will want to go with a biotin shampoo that doesn’t contain several heavy oils and instead look for a shampoo containing biotin and saw palmetto.

For those men with a thinner hair type, then a shampoo relying on volumizing agents like aloe vera will do wonders in making your hair appear much thicker. Men with a normal hair type should be fine in going with most shampoos.

4. Ingredients You May Want to Avoid

Beyond the inclusion of biotin, there are a few other ingredients you should be aware of when making your purchase. The healthiest shampoos for your scalp and hair should be free of abrasive additives that may cause mild skin irritation.

  • Parabens: Found in mass-produced shampoos, parabens act as a preservative to prevent the growth of bacteria when shampoos sit on the shelf for extended periods (source). According to the FDA, parabens have not been conclusively linked to any adverse side effects. However, men who like a clean ingredient list try to avoid parabens when possible. Parabens are easy to spot as they are often added as the suffix of the ingredient (i.e. methylparaben, ethylparaben, propylparaben, etc.). Some men with skin conditions such as dermatitis or rosacea have reported that parabens cause some mild skin irritation.
  • Sulfates: Sulfates are surfactants that produce thick suds and lather effect in shampoos, giving us great visual feedback that the shampoo is working. While erroneously claimed to be a carcinogen, there are currently no studies that support the link between sulfates and cancer. With that being said, sulfates, when used excessively can cause irritation and dry skin. Therefore, if you decide to buy a hair loss shampoo that contains sulfates, don’t use it excessively. Examples of sulfate ingredients include Sodium Cocoyl Sarcosinate, Alkylbenzene Sulfonate, Sodium Lauryl Sulfoacetate.
  • Silicone: Silicone is a tricky ingredient that trips up a lot of people. Silicone is great at providing a slick and slippery texture. However, silicone provides no real skin or hair benefits and is often used instead of pricer natural oils. While silicone can make your hair appear both smooth and shiny, it isn’t in the long run and is just a cover. When used repeatedly, silicone can build up on the scalp and hair roots to ultimately make it look and feel both brittle and dull.
  • Excess Oils: Men with naturally oily or thick hair will want to look for an oil-free shampoo. Adding more oils to your hair repeatedly can cause it to look greasy. While they are great moisturizers for both skin and hair, try to avoid common oils like jojoba, argan, pumpkin seed, grapeseed seed, and others.

5. Bottle Size

Shampoo bottles come in all shapes and sizes. Many of the leading brands offer their shampoos in multiple sizes making it easy to have one for travel or gym use and one for home. If you are happy with a particular shampoo or have had positive results in the past, larger bottles will provide greater savings.

If you are looking for a travel bottle, make sure it’s under the TSA required 3.4 oz so you don’t have to check your bag at the airport.

6. Brand

Based on our research, we found the following biotin shampoo brands to be the most popular and trusted with men:

COMPANYYEAR FOUNDEDLOCATION
Maple Holistics2001Farmingdale, New Jersey, USA
Renpure2008Vaughan, Ontario, CA
Avalon Natural Products1989Petaluma, California, USA
R+Co2014Miami, FL, USA
OGX2006Clearwater, FL, USA
Hask2012New York, NY, USA

7. Price

The price you should expect to pay for a biotin shampoo varies. However, we found the general price range to be between $5 and $40 per bottle. High-priced biotin shampoos are often from designer houses and feature a clean and pure ingredient list. Cheap biotin shampoos contain fewer ingredients and may rely on low-priced filler ingredients. Bottle size also has an impact on the price as well.

8. Features/Extras

Many biotin shampoos are very similar to one another, however, here are a few things that set them apart from one another:

Socially Responsible Brands: If you ever wanted to vote with your wallet, then this is a good opportunity. A variety of shampoo brands take on socially responsible initiatives. Whether it’s through cruelty-free research and development, relying on natural and organic ingredients, sustainable packaging measures, or simply made in the United States, chances are that you will find a shampoo that supports your values.

2-in-1 Shampoo & Conditioner: With men constantly adding new steps to their total grooming regimen, it is welcomed when a product can make things simpler. As highlighted in our reviews, some shampoos also act as a conditioner. Not only will this save time, but the added conditioner can help to make your hair look and feel healthy through increased moisture. Men with thick and oily hair may want to avoid these compounds as they may cause buildup on the scalp.

Additional Vitamins: You will find that many shampoos have additional vitamins and minerals to increase strength and health of your hair. Common ingredients that are often paired with a biotin shampoo include collagen to increase volume, Vitamin E for overall skin and hair health, and Vitamin B5 to increase moisture and shine.

Money-Back Guarantee: It’s always great when a company stands by their product, especially if you find the results lacking. Therefore, if you want to make sure you don’t waste your hard-earned cash, check what the return terms are before purchase.

  • This Shampoo contains a TON of natural and organic ingredients

From aloe vera to saw palmetto, this rich combo of ingredients has everything to build thickness in a thinning hair line. As mentioned earlier, saw palmetto is one of the few natural ingredients that has been found to increase hair growth. When you combine saw palmetto with plant protein and vitamin E, you should expect thickness and strength along the entire hair shaft.

  • Quality control unmatched in this industry

When it comes to governing the beauty industry, the government provides very little oversight and leaves the brands to self-disclose however much they want about their products. Naturally, this can cause some distrust, especially when it comes to the hair loss market. To help quell any concerns on quality control, you will be happy to learn that this biotin shampoo carries an NSF/ANSI 305 certification. What does this mean? What you see on the ingredient list is accurate. Furthermore, those disclosed as organic, are organic. It’s an added bit of quality control that we were happy to see.

  • How this shampoo improves your hair

While the reasons you are likely buying a shampoo doesn’t have to do with the ingredients and quality control, the important stuff will be the results (or any signs of improvement when it comes to hair loss).

8. Pure Biology Premium Hair Growth Shampoo

Key Facts

  • Contains natural DHT Blockers
  • Designed to add volume and thicken hair
  • Works on all hair types

Best For…

Men who want to fight their genetics with a natural DHT blocking and biotin shampoo for hair growth.

Summary

Designed to stimulate hair growth and to prevent breakage, this shampoo by Pure Biology is perfect for those looking to not only strengthen existing hairs but to slow down hair loss by blocking DHT. In addition to these key properties, this shampoo is rich in a keratin complex (Amino Kera NPNF Keratin) that helps to revive damaged hair as well.

  • Contains a natural alternative to minoxidil

Many men try to avoid minoxidil due to the application and common side effects (i.e. heart palpitations). In this bottle, you will find Procapil, A natural alternative to minoxidil that helps to increase blood flow and target both follicle aging and atrophy. While the claims seem promising, we only found one study on the NIH website that says that the evidence still has yet to be proven when it comes to procapil. Be that as it may, if you are trying to avoid minoxidil and are looking for other options, then this can be worth giving a try.

  • Made in the USA

Unfortunately, so many shampoos are made in faraway countries halfway around the world. The problem with this is that quality controls are often lax which can lead to mismeasured ingredients and inconsistent results. Therefore, when a grooming product is made in the USA, it not only sets itself apart from so many others but also brings with it naturally better quality control and shorter shipping times. Therefore, for those who want added peace of mind (and to support your local economy), you will be happy to find that this shampoo is made in the USA. To make the deal even sweeter, Pure Biology makes this shampoo in an FDA Registered Facility.

Pros

  • DHT Blocker shampoo that has seen great results among men

What You Need To Know

Designed to reduce hair thinning and complete loss, this DHT blocking shampoo coupled with a natural alternative to minoxidil makes it a great shampoo to check out. While it is a bit on the expensive side, with regular use, you should see both hydration and volume make your hair look fuller and softer.

Common Natural Ingredients Found in Biotin Shampoos (And What They Do)

The ingredients found in shampoos vary greatly from one brand to the next. Here we wanted to go over some common ingredients and their purpose:

1. Coconut Oil

Full of essential fatty acids, coconut oil helps your hair grow longer, thicker and faster. Naturally non-comedogenic (doesn’t clog pores), this oil also helps to give your hair a nice natural and healthy shine without looking or feeling greasy.

2. Jojoba Oil

Closely mimicking the natural sebum oil that your scalp produces, jojoba oil helps to nourish and moisturize your scalp and hair follicles. Found in a variety of men’s grooming products including beard oil, bar soaps, deodorants, and more, jojoba oil has a very mild scent and is great for men across many different hair types including dry hair.

3. Tea Tree Oil

Tea tree oil is an essential oil that is also a natural antiseptic. Helping to naturally combat dandruff and other scalp conditions, this oil helps to promote scalp health and has a nice light woodsy scent.

4. Argan Oil

Like jojoba oil, argan oil is another mildly scented oil that closely resembles the natural oils your skin produces. Often sourced from Morocco, argan oil is derived from a nut. According to the Food Allergy Research & Education website, guys with nut allergies rarely showed reactions when applying this ingredient. When it comes to hair health, argan oil has been claimed by many to hydrate and soften hair.

5. Essential Oils

Essential oils come in many different scents and sources. While many of their medicinal uses have yet to be proven, some men swear by their effectiveness. Our recommendation here is to not put too much weight on essential oils and instead select by scent. Common essential oils found on ingredients lists include rosemary oil, cedarwood, pearl essence, cumin seed oil, green tea extract and many more.

6. Wheat Protein

Hydrolyzed wheat proteins are found in many shampoos for hair growth. Able to naturally add volume to thinning hair, they will make any hair strand look visibly thicker. Wheat protein has also been found to increase the flexibility and strength of your hair.

7. Evening Primrose Oil

Found in medicinal shampoos, evening primrose oil is used to treat eczema, psoriasis, acne, and other skin conditions. Should you find that your scalp regularly flakes and dandruff shampoos have shown very little effectiveness, then picking up a bottle with this oil may be worth trying.

8. Aloe Vera

Containing proteolytic enzymes, aloe vera repairs dead skin cells on your scalp while also working to condition and volumizing your hair follicles. Found in beauty products for both men and women, aloe vera is a great natural alternative to chemical-based ingredients. Furthermore, aloe vera contains powerful antioxidants that will work hard to inhibit bacterial growth.

9. Castor Oil

While the natural antifungal and antibacterial benefits of castor oil are widely known, castor oil has been also known to stimulate hair growth and prevent hair loss thanks to the high concentration of ricinoleic acid.  Should you be looking for an effective natural hair shampoo, then one with a high concentration of castor oil could be helpful in providing you with fuller hair.

Biotin Shampoo: Must-Have Accessories

Since you are in the middle of researching for a brand new shampoo to work into your grooming routine, it may be worth making upgrades in other areas as well. Here are a few additional products you may want to consider:

Biotin Conditioner

While a biotin shampoo can be great for making your hair healthier and building volume, too many men for one reason or another never use a conditioner. Biotin conditioners are just as important as shampoo and need to be worked into your grooming routine. A quality conditioner helps to keep hair healthy by reducing the friction and by delivering vital nutrients. When regularly using a conditioner, your hair will also feel and look significantly better. To get the best results, it is recommended that you match your conditioner to your shampoo brand.

Leave-In Hair Product

While most conditioners are intended to be used while in the shower, leave-in conditioners are a great alternative that can be applied to your damp and dry hair once you’ve stepped out of the shower. Leave-in conditioners not only deliver all the great benefits that standard conditioners deliver, but a good leave-in conditioner also helps to protect against heat damage, which can be very important if you blow-dry your hair regularly.

Hairbrush or Hair Comb

A vital tool when it comes to both detangling and styling, hairbrushes and combs help to keep things kempt. Since you are likely looking to add volume to your hair, we recommend going with a hairbrush over a comb. A hairbrush will help to pull the hair away from the scalp whereas a comb tends to keep your hair matted down.

Hair Dryer

If you have long hair or simply want to have picture-perfect hair quickly. A hairdryer can help dry your hair and lock your style into place. But you must exercise some caution when using a hairdryer. Overuse or too much heat can dry out both your skin and hair – which may cause dandruff and severe hair damage or hair breakage.

Biotin Shampoo FAQs

Here are a few questions men had about biotin shampoos:

What is the best biotin shampoo?

The best biotin shampoo will be one that meets the needs of your hair and scalp. It is important to note that no biotin shampoo on the market will regrow all your lost hair. However, a quality biotin shampoo like those reviewed in this guide can be helpful in both building volume and strength.

Unless stated otherwise, like many off-the-shelf shampoos, you should have no problem using this type of shampoo daily.

What is the best shampoo for hair loss?

The perfect shampoo for hair loss is one that contains a careful balance of proven ingredients that add volume and foster new growth. As covered in this guide, there are many natural and chemical-based ingredients that help to slow down or reverse hair loss. 

Can hair grow back after thinning?

If the roots of the hair follicle have died, then it won’t be possible to regrow hair. Products like Rogain (active ingredient minoxidil) work by enlarging existing follicles and stretching the growth stage (anagen phase) of the hair follicle.

What does a certain shampoo ingredient do?

When it comes to figuring out why an ingredient was included in a shampoo, you shouldn’t need a degree in chemistry to try and make sense of it all. As we researched various shampoos, some head scratching ingredients we came across included cocamidopropyl betaine, sodium cocoyl glutamate, glyceryl caprylate, sodium lauroamphoacetate, and our personal favorite sodium methyl cocoyl taurat. If you want to know if an ingredient is safe, or if you want to simply want to know what it does, we highly recommend heading over to the Environmental Working Group website.

They do a great job explaining complex ingredients in detail and their key role.

What are the four hair growth phases?

The human hair goes through four stages of hair growth: anagen (growing), catagen (transition), telogen (resting), and exogen (shedding). Each stage varies in duration and to make matters more complicated, each hair on your head may be at any one of these phases.

What shampoos are bad for your hair?

To find out which shampoos you should avoid using on your hair, we recommend that you check out the Environmental Working Group (EWG), a non-profit organization that rates the impact of products within the beauty industry, for their detailed list of bad shampoos.

Biotin Shampoo vs. the Alternatives

While many men may pick up a hair growth shampoo to help aid in strength, volume, and hair growth, we wanted to share with you a few other alternatives available:

Biotin Shampoo

Based on vitamin B7, a natural biotin shampoo should be used by men who are already deficient in this vitamin and are looking to strengthen and volumize the existing hair on their head while also warding off hair loss. Popular with both men and women, this shampoo blend is a great first step to building volume for your hair without having to pay for expensive hair growth products.

Keratin Shampoo

The structural protein found in both hair and nails, keratin helps to provide a structural barrier around your hair follicle to increase both elasticity and strength (source). As a by-product of this, keratin will give your hair a much softer feel to the touch. While strengthening your hair is important, especially if it is thin, it is important to note that keratin shampoos don’t typically focus on volume.

Rogaine (Minoxidil)

Back in 1988, the FDA approved the drug Rogaine in treating baldness in men (source). With that approval, Rogaine quickly became a household name and one of the first brands men turn to when showing signs of hair loss. In 1996, the FDA approved over-the-counter sales and generic off brands to be produced under the active ingredient name, minoxidil. Men who are currently using a biotin shampoo may also want to incorporate this hair growth product into their regimen as it is one of the few hair loss products that has been proven to work. Just know that using minoxidil can be a bit laborious as it must be applied twice daily. 

Biotin Pills

Biotin supplements are another great way to close the gap should you be deficient in this vitamin. While many multi-vitamins often contain biotin under the name vitamin B7, a supplement focused on Biotin will contain far greater concentrations of this vitamin. Now it is worth noting that vitamin B7 is a water-soluble vitamin – which means that it cannot be stored in your body. Therefore, these supplements must be taken daily.

DHT Blocking Shampoo or Pills

A byproduct of testosterone, dihydrotestosterone or DHT is a hormone that causes male pattern baldness in men.

DHT is made when testosterone interacts with an enzyme found in the oils of your hair follicles (5-alpha-reductase). Once formed, DHT latches on to your hair follicles, causing them to continuously shrink over several years which eventually causes baldness.

To drastically slow down this process, companies have introduced DHT blockers in the form of both shampoos and supplements. Available over the counter, DHT blockers are the most effective hair loss treatment available per this 2017 study.

Therefore, if you are at the early stages of hair loss, it may be worth investing in a DHT blocking shampoo or supplement.

Our Criteria for Choosing the Best Biotin Shampoo

Finding the best biotin shampoo for men in 2021 proved rather difficult. With so many great natural and organic offerings available, it was hard to narrow down the field of contenders.

However, after careful consideration of several different brands along with reviewing the feedback and reviews left by other men, we are confident that our list above represents the best offerings available today.

We hope that this guide proved helpful in finding your next favorite and effective shampoo.
